3. Electrical Specification
3-1 Electrical Characteristics
The T460HW01 requires two power inputs. One is employed to power the LCD electronics and to drive
the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an
inverter.

Sequence of Power-on/off and signal-on/off
Apply the lamp voltage within the LCD operating range. When the backlight turns on before the
LCD operation or the LCD turns off before the backlight turns off, the display may momentarily
become abnormal.
Caution:
In case of handling, make sure to turn off the power when you plug the cable into the input
connector or pull the cable out of the connector.
2. The lamp power consumption shown above does include loss of external inverter at 25.
The above on/off sequence should be applied to avoid abnormal function in the display.
The used lamp current is the lamp typical current

3. The life is determined as the time at which luminance of the lamp is 50% compared to that of
Note:
The design of the inverter must have specifications for the lamp in LCD Assembly. The performance of the
Lamp in LCM, for example lifetime or brightness, is extremely influenced by the characteristics of the
DC-AC Inverter. So all the parameters of an inverter should be carefully designed so as not to produce too
much leakage current from high-voltage output of the inverter. When you design or order the inverter,
please make sure unwanted lighting caused by the mismatch of the lamp and the inverter (no lighting,
flicker, etc) never occurs. When you confirm it, the LCD Assembly should be operated in the same
condition as installed in your instrument.
Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape,
TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current
occurs between lamp wire and conducting tape.
The relative humidity must not exceed 80% non-condensing at temperatures of 40 or less. At
temperatures greater than 40, the wet bulb temperature must not exceed 39. When operate at low
temperatures, the brightness of CCFL will drop and the lifetime of CCFL will be reduced.
The output of the inverter must have symmetrical (negative and positive) voltage waveform and
symmetrical current waveform (Asymmetry ratio is less than 10%). Please do not use the inverter that has
asymmetrical voltage and asymmetrical current and spike wave. Requirements for a system inverter design
which is intended to have a better display performance, a better power efficiency and a more reliable lamp.
It shall help increase the lamp lifetime and reduce its leakage current.
a. The asymmetry rate of the inverter current and voltage waveform should be 10% below;
b. The distortion rate of the current and voltage waveform should be within 210%;
c. The ideal sine current and voltage waveform shall be symmetric in positive and negative
initial value at the typical lamp current on condition of continuous operating at 252
